WINDOW SHADE.

Application led October 1,1923. Serial No. 665,758.

To all whomtfmag/ concern.'

Be itknown that l, HERBERT lt. RArr, a citizen of the United States, residing at Sacramento, county ofSacramento, State of California, have inventedA certain new and useful improvements in Window Shades; and I do declare the following to be a full, clear, and exact description of the same, lreference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in window shades of the flexible type such as are commonly mounted on rollers, and

the use and function of which are well known in the art. v

The principal object of my invention is to provide a shade of the above named general character which can be made much cheaper than the ordinary fabric shades, and is therefore especially adapted for use in the cheaper class of lodging houses, resi-l dences and the like, and in fact 1n any building where the cost of furnishings is an item to be considered.

At the same time it is essential that such a shade be decorative andgenerally attractive in appearance, and capable of standing up well under the action of the elements.

Such a shade must also stand considerable wear and be as thoroughly opaque or impervious to light as any of the more expensive shades. y'

l attain these objects by producing the shade making material in the form of treated shade which will be a commercial success for the purposes noted the surface of the same must be of some preferably raised art-istic contour rather than plain and smooth and the treating compound must permeate through and through the paper to impregnate it to such an extent that the paper and compound will become substantially a composite or homogeneous sheet, having by reason of its make-up a tensile strength sumcient to stand the pulling to which a window shade is subjected.

ln general therefore I use a paper which is readily permeable and which has a crpemoire or other artistic surfacing. ll then treat it with a composition which toughens and water proofs the paper and renders it opaque and attractive in appearance;

-rlhe figure in the accompanying drawing paper. To be able to produce a paper is afront inner view of my improved shade mounted over a window.

ln preparing the shade l first take theI paper l in suitable form as on rolls or the like. l cut the same to a desired length and form a hem 2 at the bottom for the rece-ption of the usual pulling bar to which may be connected the usual pull cord 3.'

As stated the paper l is of a texture which renders it readily permeable by a solution, and it is saturated with my composition which, in its preferable'form, is made up as follows:

300 pounds body vpigment such as Beckton, albalith, or calalith.

12 gallons Brown 'japan dryer.

41/2 gallons boiled linseed oil.

1/2 gallon turpentine.

Suit-able coloring pigment.

rfhis forms when mixed a heavy paste.

When the paper is to be treated the above is reduced to a thin solution by mixing benzine therewith so as to make from the above formula about seventy-five gallons of the solution.

rlhe paper is immersed in any desired manner vinto the solution and being readily permeable it becomes saturated through and through therewith. rlhe benzine passing od by evaporation leaves the fibrous body of the paper impregnated or saturated with the heavy pasty mass of the composition, so that as it dries out the whole is converted into a homogeneous sheet which is opaque, water and sun prooie and of good tensile strength with an attractive surface of desired color. Also due to this thorough impregnation the cplmposition will not peel or scale fromr the' s eet.

The pigment of the composition of course is the pore filling agency; the japan dryer is the drying, adhesive and glossing agency forming the binder for the elements; the turpentine and benzine are the solvents; while the linseed oil gives pliable flexibility andfinish.

The crpe-moire vsurface LiL- 5, in addition to lending artistic effect, greatly aids in the stiffening and toughening of the product, as the shade is made up to have the crinklesl: extend longitudinally with the pull thereon. Furthermore these crinkles form innumerable crevices for the reception of and saturation by the treating composition. i 4

The naturally finished side edges of the roll of paper used'in making the shade, also form the side or vertical edges of the later.

VIf desired, however, stitching may be run up along thel side edges before the composition is applied as at 7, which stitching, being continuous, strengthens the paper, and being subsequently coated and saturated with the composition, isA thus notv only preserved against deterioration, but being bound to the paper by the adhesive in the composition, becomes practically a part of the paper.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the inventionhas defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. A window shade consisting of a readily ,permeable paper having a crpe-moireJ surface and saturated with a paint composi- 1,545,eo3 y tion to form a homogeneous opaque and flexible sheet. l v

2. A window shade comprising a paper sheet saturated with a paint composition, the sheet having means for strengthening the same longitudinally and providing a relatively large cross-sectional area for the reception of the saturating composition.

3. A window shade comprlsing a readily permeable paper sheet provided with longitudinally disposed crinkles, the sheet being saturated with a paint composition.

4. A window shade comprising a readily permeable paper saturated with a composition including a bod element, japan dryer, and boiled linseed-oi 5. Window shade material comprising enmg ribs, such paper being saturated with a paint composition to form the whole into a homogeneous opaque and flexible sheet, and continuous stitching arranged along the edge of the sheet longitudinally thereof to arrest any transverse tearing of the sheet.

In testimony whereof I aliix my signature.-
